Nope!

It only stopped me from walking into the prompt.


My own electric commands look like the following piece of code.

      (defun minibuffer-electric-tilde ()
        (interactive)
        (if (eq ?/ (preceding-char))
            (delete-region (point-min) (point)))
        (insert ?~))

The commands are added to a minor mode keymap enabled using
`minibuffer-setup-hook'.

Oh, well, the problem is that the code assumes that only the file name
is present in the buffer and hence tries to delete everything from
`point-min' to the `point'.  In order to make it work for the new
situation would be to replace `point-min' with something like
`minibuffer-prompt-end', or similar.

To write my own `minibuffer-prompt-end' would not be that much of a
problem, except that 1) if one already existed that would be better to
use, and 2) I would have to rely on the internal workings of the
current implementation, making it likely that my code would fail in
the future if the implementation would change.
